You want to build a Kubernetes Operator for your software. Which tool to choose from? Operator SDK with Helm, Ansible, or Go?

You can use Hazelcast clients in various cases, including, but not limited to the following: Building a multi-layer cache for your applications […]
Today we’re releasing Hazelcast Jet 4.3, our fourth release of 2020!

From Wikipedia, Reactive Programming is “a declarative programming paradigm concerned with data streams and the propagation of change.” The programming model is complex to master. It requires a lot of experience to feel comfortable with it. However, there’s no denying that it fits the cloud ecosystem perfectly. Since on-premises infrastructure is oversized, running a program […]
Google Summer of Code (GSoC) is a summer initiative that allows students to obtain a first deep dive into Open Source projects. It has several benefits: GSoC creates bonds between students and Open Source communities. Some, but not all, students continue to contribute to the Open Source project they worked on after GSoC This initiative […]
Imagine a client-server system that involves reading values from a data store. In the event of a connection failure with the server, the system will not be reading values. The consequences of such an event might be quite significant, including potentially costing money for a financial institution or time for a time-critical operation. If a […]
